FIGS. 10-12 and 14-19 show another exemplary illustrated embodiment of awashable diaper generally indicated by the reference numeral 110.Exemplary washable diaper 110 is similar to washable diaper 10 describedabove in connection with FIGS. 1-9, and therefore like referencenumerals preceded by the number “1” are used to indicate like elements.The description above with reference to exemplary washable diaper 10 maytherefore apply to particular components, systems, features or the likeof exemplary washable diaper 110 and is not repeated hereinafter forbrevity. Like exemplary illustrated washable diaper 10, exemplaryillustrated washable diaper 110 includes an exemplary outer article 120and an exemplary inner liner system 140.

As illustrated in FIG. 10, one exemplary embodiment of washable diaper110 may be an assembly of an outer article 120 and an inner liner system140. The inner liner system 140 may be any system or component that iscapable of mating with the outer article 120 such that the washablediaper 110 can be worn by a user. As shown best in FIG. 14, the innerliner system 140 may include at least one of an absorbent pad 170, awashable article 150 and a liner member 160. As discussed further belowwith respect to FIGS. 14-16, in some embodiments the at least onewashable article 150 may include an opening 155 in communication with acavity 154. The opening 155 and cavity 154 may be configured to acceptand retain at least one absorbent pad 170 therethrough/therewithin atleast when the inner liner system 140 is assembled with the outerarticle 120 to form the washable diaper 110. As also discussed furtherbelow, the at least one washable article 150 may be configured (e.g.,the opening 155 and cavity 154 may be configured) such that the at leastone absorbent pad 170 is easily removable, such as being consistentlyremoved during a wash cycle of a typical washing machine.

As shown in FIGS. 10-12, 14 and 17, the outer article 120 may includefront compartment, flap, pouch or pocket 123 at a front end 121 and asecond compartment, flap, pouch or pocket 124 at a second end 122. Thefirst and second compartment 123, 124 may be formed, at least in part,by a first member, component, portion or material 185 and a secondmember, component, portion or material 186 adjacent or laying over thefirst member 185. In this way, first and second compartment 123, 124 areformed by the space or area between the first and second member 185,186. The front and back ends 121, 122, may also include at least onestiffening member or configuration such that the front and back ends121, 122, and the portions proximate thereto, are relatively stiff ascompared to portions without the stiffening members and, thereby, areprevent from folding or otherwise deforming into a “closed” orientation.

In some embodiments, the first member 185 may be a portion of the innerlining or material that forms the inner surface 129 of the outer article120, as shown in FIGS. 10-12, 14, 16 and 17. As described above, theinner surface 129 may be substantially liquid impervious. In such anembodiment, the inner surface 129 may span substantially along theentire length of the outer article 120. In contrast, the second member186 of the first and second compartments 123, 124 may be substantiallyaligned along the first and second ends 121, 122, respectively, of theinner surface 129 (and therefore the outer article 120 itself), but mayonly extend partially towards the longitudinal center of the outerarticle 120. The second portion 186 may therefore be the portion of theinner surface 129 that lies adjacent to the first portion 185. In thisway, the first and second compartments 123, 124 may be positionedadjacent the first and second ends 121, 122 of the outer article 120,respectively, and a medial portion 139 of the inner surface 129 of theouter article may be void (or not covered by the second portion 186), asshown in FIGS. 11, 12 and 14.

The first and second compartment 123, 124 may be include an opening thatfaces the medial portion 139 of the outer article 120 (and the innersurface 129), as shown in FIGS. 10-12 and 14. However, besides theopening or passageway facing the medial portion 139 of the outer article120, the first and second compartment 123, 124 may be operably coupledsuch that the first and second compartments 123, 124 formed therebetweenis substantially “closed”. In the exemplary illustrated embodiment, thefirst and second compartment 123, 124 are “closed” (apart from themedial openings) such that they are substantially liquid impervious.

As shown best in FIGS. 10 and 11, the first and second compartment 123,124 (e.g., the first and second portions 185, 186) may be “sealed”(except for the medial facing openings), at least in part, by banding180. As illustrated in FIGS. 10-12 and 16-19 and described furtherbelow, banding 180 may be a substantially liquid imperious material,assembly or the like that is applied over a seam, joint, edge or thelike. For example, in some embodiments the banding 180 may besubstantially liquid impervious fabric material. The banding 180 may beapplied such that the banding 180 seals a joint seam, edge or the like,such as a creating a substantially liquid impervious seal. In someembodiments, banding 180 may be applied over a seam, joint, edge or thelike by stitching, such as being stitched with substantially non-wickingthread via a needle. In some exemplary embodiments, the non-wickingthread may be a polyester thread and the needle may be a ball needle. Inthis manner, banding 180 may be applied to seams, edges, joints or thelike of the outer article 120, including any such connections betweenthe first and second portions 185, 186 of the first and secondcompartments 185, 186 to substantially prevent liquid from migratingthrough the outer article 120 via a seam, joint, edge or the liketherein. In other embodiments, seams, edges, joints or the like of theouter article 120 (or any other component) may be “sealed” in anotherknown manner such that they are substantially liquid impervious.

In the illustrated exemplary embodiment best shown in FIGS. 10-12 and14, the first and second compartment 123, 124 of the outer article 120extend substantially along the entire width of the outer article 120 andinclude banding 180 applied to the first and second portions 185, 186 onthe opposing side edges 125, 126 of the outer article 120 (and thereforethe first and second compartment 123, 124). In some embodiments, thebanding 180 itself is substantially liquid impervious, and the banding180 is applied to the opposing side edges 125, 126 of the first andsecond portions 185, 186 in a manner that seals the opposing side edges125, 126 of the first and second portions 185, 186 such that liquid issubstantially prevented from migrating therethrough. In this way, theopposing side edges 125, 126 of the first and second compartment 123,124 may be substantially liquid impervious. For example, the banding 180may be sewn over the opposing side edges 125, 126 of the first andsecond portions 185, 186 with non-wicking thread (such as with a ballneedle).

As described above, the first and second members 185,186 of the firstand second compartments 123, 124 may be substantially aligned along thefirst and second ends 121, 122, of the outer article 120. For example,if the first and second members 185,186 are separate and distinctcomponents, they may be substantially aligned along the first and secondends 121, 122, of the outer article 120. In such an embodiment, thefirst and second ends 121, 122 of the first and second members 185,186may be coupled to one another, such as sealed to one another. Forexample, as shown in the illustrated exemplary embodiment of the outerarticle 120 in FIGS. 10, 11, 14, 16 and 17, the first and second ends121, 122 of the first and second members 185,186 of the first and secondcompartment 123, 124 may include banding 180. In some such embodiments,the banding 180 itself is substantially liquid impervious, and thebanding 180 is applied to the first and second ends 121, 126 of thefirst and second portions 185, 186 in a manner that seals the first andsecond ends 121, 122 of the first and second portions 185, 186 such thatliquid is substantially prevented from migrating therethrough. In thisway, the first and second ends 121, 122 of the first and secondcompartment 123, 124 may be substantially liquid impervious. Forexample, the banding 180 may be sewn over the opposing first and secondends 121, 122 of the first and second portions 185, 186 with non-wickingthread (such as with a ball needle). In some embodiments, the mechanismthat couples the banding 180 to the outer article 120 also acts tocouple the first and second portions 185, 186 to one another. Forexample, in embodiments wherein the banding 180 is applies to the firstand second ends 121, 122 via thread, the thread may also act to couplethe first and second portions 185, 186 to one another (i.e., the threadmay stitch the first and second portions 185, 186 at the first andsecond ends 121, 122.

In some embodiments of the outer article 120, such as the illustratedexemplary embodiment of FIGS. 10-12 and 14, the first and second members185,186 of the first and second compartment 123, 124 may be integral,monolithic, one-piece or the like. In such an embodiment, the first andsecond members 185,186 may be substantially liquid impervious (e.g., theinner surface 129 may be substantially liquid impervious) and foldedover upon themselves at the first and second ends 121, 122. The “foldline” between the first and second members 185,186 may thereby define,at least in part, the first and second ends 121, 122 of the first andsecond compartment 123, 124 (and therefore outer article 120 itself).Also, the “fold line” between first and second members 185,186 maydefine the bottom of the first and second compartment 123, 124 whichopposes the openings facing the medial portion 139 of the outer article120. In this way, the first and second ends 121, 122 may besubstantially liquid impervious. However, for aesthetics and/or wearprevention, in the some embodiments the first and second members 185,186of the first and second compartment 123, 124 may be integral and the“fold line” between first and second members 185,186 may include banding180, as shown best in FIGS. 10-12 and 14. For example, the entireoutline or outer edges of the outer article 120 may include banding 180,such as singled piece or potion of banding sewn over the entire outlineor outer edges of the outer article 120.

As shown in FIG. 10, the first end 141 of inner liner system 140 may bealigned with the front end 121 of the washable article 120 andpositioned within the front compartment 123. To this end, the frontcompartment 123 may configured to receive the first end 141 of the innerliner system 140 therein. For example, the second member 186 of thefront compartment 123 may extend along the width of the outer article120 (a direction extending between the opposing side edges 125, 126 ofthe washable article 120) a sufficient distance such that the width ofthe inner liner system 140 is substantially the same or smaller. In theexemplary illustrated embodiment best shown in FIG. 10, the width of thesecond member 186 of the front compartment 123 is about equal to thewidth of the outer article 120 and the first member 185 and greater thanthe width of the inner liner system 140, as indicated by the dashedlines representing the outer edges of the inner liner system 140 in thefirst compartment 123. Similarly, in the illustrated embodiment thesecond member 186 of the front compartment 123 extends along the lengthof the outer article 120 (a direction extending between the first andsecond ends 121, 122 of the washable article 120) a distance such that arelatively substantial portion of the length of the inner liner system140 can be positioned within the first compartment 123, as indicated bythe dashed lines representing the outer edges of the inner liner system140 in the first compartment 123 in FIG. 10. In this way, the first end141 of the inner liner system 140 may be positioned substantially withinthe first compartment 123 such that any liquid flowing through, orforced from, the first end 141 of the inner liner system 140 (or aportion adjacent thereto) becomes trapped or held within thesubstantially liquid impervious first compartment 123.

The second compartment 186 of the outer article 120 may be configuredsubstantially similar to the first compartment 185 of the outer article120, such as described above. Specifically, as shown in FIG. 10 thesecond end 142 of inner liner system 140 may be aligned with the secondend 122 of the washable article 120 and positioned within the backcompartment 124. To this end, the back compartment 124 may configured toreceive the second end 142 of the inner liner system 140 therein. Forexample, the second member 186 of the back compartment 124 may extendalong the width of the outer article 120 (a direction extending betweenthe opposing side edges 125, 126 of the washable article 120) asufficient distance such that the width of the inner liner system 140 issubstantially the same or smaller. In the exemplary illustratedembodiment best shown in FIG. 10, the width of the second member 186 ofthe back compartment 124 is about equal to the width of the outerarticle 120 and the first member 185 and greater than the width of theinner liner system 140, as indicated by the dashed lines representingthe outer edges of the inner liner system 140 in the second compartment124. Similarly, in the exemplary illustrated embodiment the secondmember 186 of the second compartment 124 extends along the length of theouter article 120 (a direction extending between the first and secondends 121, 122 of the washable article 120) a distance such that arelatively substantial portion of the length of the inner liner system140 can be positioned within the second compartment 124, as indicated bythe dashed lines representing the outer edges of the inner liner system140 in the second compartment 124 in FIG. 10. In this way, the secondend 142 of the inner liner system 140 may be positioned substantiallywithin the second compartment 124 such that any liquid flowing through,or forced from, the second end 142 of the inner liner system 140 (or aportion adjacent thereto) becomes trapped or held within thesubstantially liquid impervious second back compartment 124.

As shown in FIGS. 11, 12 and 14 with the inner liner system 140 notassembled with the outer article 120, the inner surface 129 may besubstantially void and the first and second compartments 123, 124 mayinclude at least one fastening mechanism 131 positioned therein. InFIGS. 11, 12 and 14, the at least one fastening mechanism 131 is shownin dashed lines representing its positioning under second member 186.FIG. 12 also shows the second member 186 of the first and secondcompartments 123, 124 partially cut away to reveal the at least onefastening mechanism 131 beneath. The at least one fastening mechanism131 may be coupled to the outer article 120 by any means, and may takethe form of any known fastening mechanism in the art. As non-limitingexample, the at least one fastening mechanism 131 may be at least onehalf or mate of a hook and loop fastener, such as a Velcro® brand hookand loop fastener system, a hook and eye fastener, pin fastener, buttonfastener, snap button or clasp mechanisms, or the like. In theillustrated exemplary embodiment, the at least one fastening mechanism131 is one half or the mate of a press, spring or snap button that facesaway from the first portion 185 and toward the second portion 186.Further, the number and positioning of the at least one fasteningmechanism 131 may vary. For example, the at least one fasteningmechanism 131 may or may not be positioned within the first and secondcompartments 123, 124. As another example, multiple fastening mechanisms131 may be provided, such as being provided within the first and secondcompartments 123, 124. Still further, at least one fastening member 131may be provided in one of the first and second compartments 123, 124.The at least one fastening mechanism 131 may be configured to detachablycouple the inner lining system 140 to the outer article 120. Morespecifically, the at least one fastening member 131 may be configured todetachably couple the inner liner system 140 to the outer article 120such that the first end 141 of the inner liner system 140 and anadjacent portion of the inner liner system 140 is positioned andselectively secured within the first or front compartment 123, and suchthat the second end 142 of the inner liner system 140 and an adjacentportion of the inner liner system 140 is positioned and selectivelysecured within the second or back compartment 124.

In the illustrated exemplary embodiment, the first or front and secondor back compartments 123, 124 include a pair of fastening mechanisms 131spaced along the width of the compartments 123, 124, as shown in FIGS.10-12, 14 and 17. As shown best by the cutaway view of FIG. 12, theillustrated exemplary outer article 120 includes a pair of fasteningsupport members 182 coupled to the outer article 120, and each fasteningsupport member 182 includes a fastening mechanism 131 coupled theretoand positioned within the respective first or second compartment 123,124. In some embodiments, the fastening support members 182 may beflexible, and may extend from the respective first or second ends 121,122. For example, the fastening support members 182 may include fabric,at least in part, and may be secured to the outer article 120 at therespective first or second ends 121, 122. In some such embodiments, themechanism that couples the first and second portions 185, 186 to oneanother also couples the fastening support members 182 to the outerarticle 120. For example, in the illustrated exemplary embodiment shownbest in FIG. 12 the first and second portions 185, 186 of the first andsecond compartments 123, 124 are coupled to one another (besides beingintegral) by banding 180 being stitched over the first and secondmembers 185, 186 at the first and second ends 121, 122, respectively,and the fastening support members 182 are positioned between the firstand second portions 185, 186 and aligned at the first and second ends121, 122 such that the stitching also passes through the fasteningsupport members 182. However, in other outer article 120 embodiments thefastening support members 182 may be coupled to the outer article my anyknown mechanism or method known in the art. Further, the fasteningsupport members 182 may not be provided, or may not be provided in thefirst and second compartments 123, 124. For example, the fasteningmechanism 131 may be provided on the outer article 120 by any otherknown mechanism or method, such as being coupled to the inner surface129 of the outer article, such as to the inner surface 129 of the firstor second members 185, 186.

As illustrated best in FIGS. 10-12, 14 and 16, the outer article 120 mayinclude first and second opposing side barriers 127, 128 at the medialportion 139 of the outer article 120. The first and second side barriers127, 128 may extend from the first and second opposing side edges 125,126 of the outer article 120, respectively, in a direction extendingfrom the outer surface 130 toward the inner surface 139 (i.e., towardthe wearer). The opposing side barriers 127, 128 may thereby furthersecure the inner liner system 140 in the outer article 120 so that innerliner system 140 does not shift or move when washable diaper 110 isworn. The opposing side barriers 127, 128 may thereby also operate toenhance the containment of urine and other bodily excrements in theouter article 120, and consequently operate to enhance the absorption ofbodily excrements by the inner liner system 140. In the illustratedexemplary embodiment, the side barriers 127, 128 are distinct ordiscrete components coupled to the outer article 120. In some suchembodiments, the side barriers 127, 128 may be panels tapered at one orboth ends with an inner curved surface coupled to the opposing sideedges 125, 126 of the inner surface 129, as shown best in FIGS. 11 and20-22 and described further below. The side barriers 127, 128 may becoupled to the opposing side edges 125, 126 of the outer article 120,respectively, by banding 180. For example, as shown best in thecross-sectional view of the outer article 120 of FIG. 10 in FIG. 16, thecurved edge of the side barriers 127, 128 may in abutment with the innersurface 129 of the outer article 120 and banding 180 may be stitched 184over the outer article 120. More specifically, stitching 184 may passthrough an inner portion of the banding 180, the respective side barrier127, 128, the inner surface 129 and an outer portion of the banding 180as shown in FIG. 16. If the outer article 120 includes one or moreadditional layers above the inner layer 129, the stitching 184 may passthrough the additional layers as well.

The way in which the side barriers 127, 128 are attached to the outerarticle 120 may tend to force or encourage the side barriers 127, 128 toextend away from the inner surface 129 toward the body of a wearer,thereby providing a curved shape to the outer article 120 such that themedial portion 139 of the outer article forms a depression or cuppedregion. For example, the stitching 184 and banding 180 configurationshown in the cross-sectional view of FIG. 16 may act to force the outeredges of the side barriers 127, 128 to extend away from the innersurface 129 to form a “U” shape. By extending away from the innersurface 129 of the outer article, the side barriers 127, 128 may providea space between the wearer and the inner surface 129 for the inner linersystem 140 and the anatomy of the wearer so that the outer edges of theside barriers 127, 128 abut and conform to the wearer and preventleakage.

The side barriers 127, 128 may include an elasticized member or portion188 which may additionally contribute to the positioning of the sidebarriers 127, 128 away from the inner surface 129 of the outer article120. Further, the elasticized member or portion 188 of the side barriers127, 128 may tend to cup or bow the outer article 120 in the lengthdirection from the front or first side 121 to the second or back end122, as shown best in FIG. 11. The cupping or bowing of the outerarticle 120 in the length direction may enhance the fit and comfort ofthe washable diaper 110. For example, the elasticized side barriers 27,28 may be configured to conform to the legs of the wearer and minimizepotential leakage out from within the interior of the outer article 120.

In some embodiments, as shown in FIGS. 10-12, 14 and 16 the elasticizedmember or portion 188 of the side barriers 127, 128 may be the outeredges of the side barriers 127, 128. The elasticized member or portion188 of the side barriers 127, 128 may take any form such that in aneutral position the elasticized member or portion 188 is capable ofbeing stretched at least lengthwise so the outer article 120 “flattens”out. Stated differently, the elasticized member or portion 188 of theside barriers 127, 128 may take any form such that in a neutral positionthe side barriers 127, 128 tend to pull or form the outer article into acupped or bowl shape (see FIG. 11). As shown in FIG. 11, the exemplaryelasticized member or portion 188 of the exemplary illustrated sidebarriers 127, 128 is an elasticized member 188 coupled to the outeredges of the side barriers 127, 128. Further, as shown in FIGS. 10-12and 14 the exemplary elasticized member or portion 188 of the exemplaryillustrated side barriers 127, 128 is coupled to their respective sideedge 125, 126 of the inner layer 129 as opposing ends.

In some alternative embodiments, the outer article 120 may not includeseparate and distinct side barriers 127, 128, such as exemplary outerarticle 220 illustrated in FIG. 13. In some such embodiments, the innerlayer or surface 229 of the outer article 220 may include substantiallythe same shape and size as compared to an outer article that includesseparate and distinct side barriers coupled to opposing sides. In someembodiments however, the outer article 220 may be shaped and sizedsubstantially similar to the outer profile and size of an outer articlethat includes separate and distinct side barriers coupled to opposingsides. In this way, the side barriers may be in essences integral withthe outer article, such as integral with the inner layer or surface 229and the outer article 220 retains the advantages of the side barriers,as shown in FIG. 13. As also shown in FIG. 13, in some such embodimentsthe outer article 220 may include banding 280 about its side portionsalong an internal portion of the outer article in locations whereseparate and distinct side barriers would be attached to the outerarticle (such as to the inner surface or portion 229). In this way, theintegral side barriers 227, 228 may tend to extend away from the innerlayer or surface 229 and toward the user to include the advantageousfit, leakage and aesthetic properties or benefits described above withrespect to outer article 120 and side barriers 127, 128.

FIGS. 10-12, 14 and 19 best illustrate the shape of the exemplary outerarticle 120. The shape and size of the outer article 120, and thereforethe washable diaper 110 in general, may be configured such that thewashable diaper 110 surrounds or otherwise conforms to the legs andwaist of the wearer to maximize fit and minimize potential leakage. Forexample, the exemplary illustrated outer article 120 is configured witha generally hourglass-like silhouette with the front and back ends 121,122 including first and second opposing extended portions 136, 137,respectively, being wider than the medial portion 139. In theillustrated exemplary embodiment, the first extended portions 136, 137at the back end 122 of the outer article 120 are capable of extending orwrapping around the user's body or waist when worn, as shown in FIG. 18.The second extended portions at the second or back end 122 of the outerarticle 120 may extend further than the first extended portions 136 atthe first or front end 121 (i.e., the second extended portions 137 maybe wider than the first extended portions 136), as shown best in FIGS.10-12 and 14. In some such embodiments, when the washable diaper 110 isworn the second extended portions 137 of the back end 122 of the outerarticle 120 may wrap around the user's waist and over the outer surfaceof the first extended portions 136 and the portion extendingtherebetween (at least in part).

In order to removably couple the second extended portions 137 to anotherportion of the outer article 120, such as when the washable diaper 110is being worn by a user and thereby couple the washable diaper 110 tothe user, the second opposing extended portions 137 may include firstfastening mechanisms 133, as shown in FIGS. 10-12, 14 and 17. The firstfastening mechanisms 133 of the second extended portions 137 may be anyknown fastening mechanism capable of removably coupling the secondextended portions 137 with another portion of the outer article 120,such as a portion of the outer surface or layer 130. In some embodimentsthe first fastening mechanisms 133 of the second extended portions 137may be one part of a multiple-part fastening mechanism, such as one partof a multiple-part fastening mechanism that is configured to mate withanother part of the multiple-part fastening mechanism positioned onanother portion of the outer article 120. For example, the firstfastening mechanisms 133 of the second extended portions 137 may be onepart or member of a hook and loop fastener, such as a Velcro® brand hookand loop fastener system, a hook and eye fastener, pin fastener, buttonfastener, snap button or clasp mechanisms, or the like. In otherembodiments, the first fastening mechanisms 133 of the second extendedportions 137 may be a single-part fastening mechanism. In theillustrated exemplary embodiment best shown in FIGS. 10-12, 14, 17 and18, the first fastening mechanisms 133 comprises one part of a hook andloop fastener and extend from the second extended portions 137 out pastthe side edges 125, 126 of the outer article. As explained furtherbelow, the one or more first fastening mechanisms 133 may be configuredto removably mate, couple or attach to one or more second fasteningmechanism 134 that is provided on another portion of the outer article120, such as on the outer surface 130 and adjacent the back end 122.

In some alternative embodiments (not shown), the first fasteningmechanisms 133 may include multiple fastening mechanisms and anextension member therebetween, at least one of the multiple fasteningmechanisms for mating with the one or more second fastening mechanism134 of the outer article 120. For example, the first fasteningmechanisms 133 may include a fastening mechanism provided on theextended portions 137, and an extension member including a fasteningmechanism proximate one end of the extension member for removablycoupling with the fastening mechanism provided on the extended portions137 and another fastening mechanism proximate another end of theextension member for removably coupling with a second fasteningmechanism 134 provided on the first extended portions 136 or theportions of the outer article 120 thereabout (such as on the outersurface or layer 130 of the first extended portions 136 and/or theportion of the outer surface 130 of the outer article 120 extendingbetween the first extended portions 136 and adjacent the front end 121).In some such embodiments, the fastening mechanism provided on theextended portions 137 of the first fastening mechanisms 133 and thesecond fastening mechanism 134 may also be configured to removablecouple to one another. In such an embodiment, the first fasteningmechanisms 133 may allow the outer article 120, and therefore thewashable diaper 110, to be worn by both small and large user's becausethe extension member may or may not be used. Stated differently, in suchan embodiment the fastening mechanism provided on the extended portions137 of the first fastening mechanisms 133 and the second fasteningmechanism 134 may be directly removably coupled (without the use of theextension member) to accommodate and removably coupled the washablearticle 120 (and therefore the washable diaper 110) to a relativelysmall user, or the extension member may be removably coupled between thefastening mechanism provided on the extended portions 137 of the firstfastening mechanisms 133 and the second fastening mechanism 134 toaccommodate and removably coupled the washable article 120 (andtherefore the washable diaper 110) to a relatively large user.

The second extended portions 137 may also include another fasteningmechanism, such as third fastening mechanisms 133B shown in FIGS. 10-12,14 and 17. The third fastening mechanisms 133B may be any knownfastening mechanism. The third fastening mechanism may or may not bedeposed or operably attached to the second extended portions 137 of theinterior surface 129. The third fastening mechanisms 133B of the secondextended portions 137 may be one part of a multiple-part fasteningmechanism, such as one part of a multiple-part fastening mechanism thatis configured to mate with another part of the multiple-part fasteningmechanism. For example, in the illustrated exemplary embodiment thethird fastening mechanisms 133B of the second extended portions 137 maybe configured to mate with the first fastening mechanisms 133 on thecorresponding second extended portions 137. As the first fasteningmechanisms 133 of the second extended portions 137 of the exemplaryillustrated embodiment are one part of a hook and loop fastener, thethird fastening mechanisms 133B may be the other part of the hook andloop fastener such that the first and third fastening mechanisms 133,133B are capable of removably mating or coupling. In this manner, forexample, each second extended portion 137, first fastening mechanism 133or third fastening mechanism 133B may be deformed such that the firstand third fastening mechanisms 133, 133B lie over one another and,thereby, removably couple or attach to one another. As is known in theart, such a configuration may be advantageous if the first fasteningmechanisms 133 are configured such that they tend to attach or couplewith other portions of the washable diaper 120 or other clothes,fabrics, fastening mechanisms, etc. For example, if the first fasteningmechanisms 133 are the hook portion of a hook and loop fastener, thefirst fastening mechanisms 133 may tend to attach or couple to otherportions of the washable diaper 110 or other fabrics when the washablediaper 110 is not worn, such as when the outer article 120 is beingwashed. In such a configuration, however, the first and third fasteningmechanisms 133, 133B may be mated or coupled such that the firstfastening mechanisms 133 (or third fastening mechanisms 133B) areblocked-off or otherwise rendered incapable of coupling to otherportions of the washable diaper 110 or other fabrics, clothes fasteningmechanisms, etc.

In some such embodiments, the outer surface of the first extendedportions 136, or portions of the outer article 120 thereabout (such ason the outer surface or layer 130 of the outer article 120 extendingbetween the first extended portions 136 and adjacent the front end 121)may include one or more second fastening mechanism 134, as shown in FIG.18. The at least one second fastening mechanism 134 may be configured toremovably couple with the first fastening mechanisms 133 of the secondextended portions 137, such as when the second extended portions 137 arewrapped around a users waist and over the first extended portions 136,as shown in FIG. 18. For example, the at least one second fasteningmechanism 134 may be one part of a multiple-part fastening mechanism,such as one part of a multiple-part fastening mechanism that isconfigured to mate with another part of the multiple-part fasteningmechanism. In the illustrated exemplary embodiment the at least onesecond fastening mechanism 134 is configured to removably mate, coupleor otherwise attach to the first fastening mechanisms 133 on the secondextended portions 137. As the first fastening mechanisms 133 of thesecond extended portions 137 of the exemplary illustrated exemplaryembodiment of the outer article 120 are one part of a hook and loopfastener, the at least one second fastening mechanism 134 may be theother part of the hook and loop fastener such that the first and secondfastening mechanisms 133, 134 are capable of removably mating, attachingor coupling.

The at least one second fastening mechanism 134 may further beconfigured such that the first fastening mechanisms 133 may couple tothe portion of the outer surface or layer 130 adjacent the front end 121of the outer article 120 in different locations, and thereby accommodatedifferent sized users, fits or tightness/looseness preferences of thewashable diaper 110. For example, the at least one second fasteningmechanism 134 may include several parts of a multiple-part fasteningmechanism that are configured to mate with the first fasteningmechanisms 133 positioned in different locations on the outer surface orlayer 130 of the outer article 120. As another example, as shown in FIG.18, the at least one second fastening mechanism 134 may be sized andshaped to expand over a region of the outer surface or layer 130adjacent the front end 121 of the outer article 120, such as arelatively large portion of one part of a hook and loop fastener (i.e.,a relatively large portion of hooks or loops). As the first fasteningmechanisms 133 of the second extended portions 137 of the exemplaryillustrated exemplary embodiment of the outer article 120 are one partof a hook and loop fastener, the at least one second fastening mechanism134 may be a relatively large portion of the other part of the hook andloop fastener such that the first fastening mechanisms 133 are capableof removably mating, attaching or coupling to the second fasteningmechanism 134 in a variety of location and orientations, as indicated bythe dashed outlines of the first fastening mechanisms 133 in FIG. 18. Inthis way, the second extended portions 137 may be extended over thefirst second extended portions 136 and the front portion of the outerarticle 120 to differing extends based on the size or preference of theuser.

As illustrated in FIGS. 11, 17 and 18, the second extended portions 137may include fourth fastening mechanisms 135 positioned on the outersurface or layer 130 of the outer article 120. For example, the fourthfastening mechanisms 135 may be sized and shaped substantially similarto the first fastening mechanisms and attached directly to thecorresponding opposing side of the second extended portions 137 of theouter article 120 (i.e., the outer side 130 as opposed to the inner side129). The fourth fastening mechanisms 135 may be any known fasteningmechanisms. The fourth fastening mechanisms 135 of the second extendedportions 137 may be one part of a multiple-part fastening mechanism,such as one part of a multiple-part fastening mechanism that isconfigured to mate with another part of the multiple-part fasteningmechanism. For example, in the illustrated exemplary embodiment thefourth fastening mechanisms 135 of the second extended portions 137 maybe configured to mate with the first fastening mechanisms 133. As thefirst fastening mechanisms 133 of the second extended portions 137 ofthe exemplary illustrated embodiment are one part of a hook and loopfastener, the fourth fastening mechanisms 135 may be the other part ofthe hook and loop fastener such that the first and fourth fasteningmechanisms 133, 135 are capable of removably mating or coupling.

In this manner, for example, when the washable diaper 100 is worn andthe outer article 120 is wrapped around the user's waist and legs, thesecond extended portions 137 may overlap the first extended portions 136and the portion of the outer surface 130 extending between the firstextended portions 136 such that one first fastening mechanisms 133completely or fully couples to the at least one second fasteningmechanism 134 and the other of the first fastening mechanisms 133partially or fully overlaps it. Such a configuration may result from auser being relatively small as compared to the size of the washablediaper 110. In such a scenario, the “overlapping” first fasteningmechanism 133 may partially removably couple to the at least one secondfastening mechanism 134 and partially removably couple to the firstfastening mechanism 133 that is completely or fully coupled to the atleast one second fastening mechanism 134. In this manner, the fourthfastening mechanisms 135 may provide the outer article 120 with greaterflexibility or use with differing sized users.

Turning to the inner liner system 140, as shown in FIGS. 14-17 the innerliner system 140 may include at least one washable article 150, at leastone liner member 160 and at least one absorbent pad 170. In somealternative embodiments of the washable diaper 110, however, anabsorbent pad 170 may not be provided in the washable article 150. Theat least one washable article 150 may include any material capable ofabsorbing liquid. For example, the at least one washable article 150 inthe illustrated embodiment is made from a sewn, liquid absorbentmaterial, such as a hemp, cotton, flannel or a micro fiber fabric. Asshown best in FIGS. 14-15C and 16, the at least one washable article 150may include an opening 155 in communication with a cavity 154. Theopening 155 and cavity 154 may be configured to accept and retain atleast one absorbent pad 170 therethrough/therewithin at least while theinner liner system 140 is assembled with the outer article 120 to formthe washable diaper 110. The exemplary opening 155 and cavity 154 ofexemplary illustrated washable article 150 may be formed by the washablearticle 150 and extend longitudinally from a first end 151 to second end152 thereof. The opening 155 may be located in various positions,including on the front side, back side, or either lateral sides of atleast one washable article 150 and of any size and shape, so long asopening 155 can accommodate the insertion of at least one absorbent pad170 within the and cavity 154. For example, the longitudinal length ofthe opening 155 may or may not be longer than the longitudinal length ofthe at least one absorbent pad 170. To that end, the cavity 154 incommunication with the opening 155 may be in any position within thewashable article 150 and may be any size and shape, so long at least oneabsorbent pad 170 can be positioned therewithin via the opening 155. Inthe illustrated exemplary embodiments of the washable article 150, thelongitudinal lengths of the opening 155 and the cavity 154 are at leastabout 80% the longitudinal length of the least one absorbent pad 170.

In some embodiments of the washable diaper 110 that include at least oneabsorbent pad 170, the at least one absorbent pad 170 may include atleast one axis of substantial symmetry, such as the exemplaryillustrated absorbent pad 170 shown best in FIG. 14. In such exemplaryembodiments, the use, advantages characteristics or other performancemetrics of the at least one absorbent pad 170 may not be affected by theorientation of the at least one absorbent pad 170 along the axis whenpositioned within the washable article 150. In some embodiments,however, the at least one absorbent pad 170 may be shaped or otherwiseconfigured such that its orientation within the washable article 150 mayaffect the performance of the at least one absorbent pad 170. In someembodiments, the at least one absorbent pad 170 may be configuredspecifically for use with either male or female users. For example, theat least one absorbent pad 170 may be shaped differently for use witheither male or female users. In other embodiments, the at least oneabsorbent pad 170 may be the same for both male and female users.

Similarly, in some embodiments the cavity 154 of the washable article150 and/or the at least one absorbent pad 170 may be configured suchthat the absorbent pad 170 is positioned within the washable article 150such that when the inner liner system 140 is coupled to the outerarticle 120 the absorbent pad 170 is positioned within the medialportion 139 of the outer article 120, such as being positioned withinthe medial portion 139 of the outer article 120 in specific positionsfor use with either male or female users.

In some embodiments, the size, shape, orientation and materialproperties of the at least one absorbent pad 170 and the washablearticle 150, including the opening 155 and cavity 154 thereof, may beconfigured such that the at least one absorbent pad 170 tends to easilybecome disengaged from the cavity 154 through the opening 155 when theinner liner system 140 is not assembled with the outer article 120 orthe washable diaper 110 is worn. For example, the at least one absorbentpad 170 and the washable article 150 may be configured such that whenthe washable article 150 is removed from the outer article 120 and theother components of the inner liner system 140, and washed during atypical wash cycle of a typical washing machine, the at least oneabsorbent pad 170 becomes dislodged from within the washable article150. In this way, the at least one absorbent pad 170 may advantageouslynot need to be handled or otherwise manually removed from the washablearticle 150, such as when the at least one absorbent pad 170 andwashable article 150 are soiled.

The at least one washable article 150 may further comprise at least oneliner fastening mechanism 158 disposed on a bottom surface 161 thereof,as shown in FIGS. 14, 15 and 17, for at least partially coupling a linermember 160 thereto. For example, as shown in the exemplary illustratedembodiment a pair of side liner fastening mechanisms 158 may be providedon a bottom surface 161 of the washable article 150. The least one linerfastening mechanism 158 and the opening 154 may be provided on the sameside of the washable article 150, such as the bottom side or surface161. The at least one liner fastening mechanism 158 may be any knownfastening mechanism capable of coupling the liner member 160. Forexample, the at least one liner fastening mechanism 158 may be one partof a multiple-part fastening mechanism that is configured to mate withanother part of the multiple-part fastening mechanism. In otherembodiments, the at least one liner fastening mechanism 158 may besingular and capable of coupling the washable article 150 to a linermember 160. For example, the at least one liner fastening mechanism 158may be the hook part of hook and loop fastener, such as the Velcro®brand hook and loop fastener system. In such an embodiment, the linermember 160 may be configured to be coupled to the washable article 150via the at least one “hook” liner fastening mechanism 158, such as beinga fabric or fabric-like material.

The at least one washable article 150 may also include one moreadditional fastening mechanism in addition to the at least one linerfastening mechanism 158. For example, the at least one washable article150 may also include at least one opening fastening mechanism 158Badjacent each least one liner fastening mechanism 158 and the opening155, as shown in FIGS. 15-16. The at least one opening fasteningmechanism 158B may be any known fastening mechanism. The at least oneopening fastening mechanism 158B may be one part of a multiple-partfastening mechanism, such as one part of a multiple-part fasteningmechanism that is configured to mate with another part of themultiple-part fastening mechanism. For example, in the illustratedexemplary embodiment the at least one opening fastening mechanism 158Bmay be configured to mate with the at least one liner fasteningmechanism 158. As the at least one liner fastening mechanism 158 of theexemplary illustrated washable article 150 may be one part of a hook andloop fastener adjacent opposing longitudinal sides of the washablearticle 150, the at least one opening fastening mechanism 158B may bethe other part of the hook and loop fastener such that the adjacentopening fastening mechanisms 158B and liner fastening mechanisms 158 arecapable of removably mating or coupling. In this manner, for example,the washable article 150 may be deformed such that adjacent openingfastening mechanisms 158B and liner fastening mechanisms 158 areremovably coupled or attached and, thereby, the opening 155 is “pulled”to an “open” position as partially shown in FIG. 14 (as compared to the“closed” state shown in FIG. 16).

As is known in the art, such a configuration may be advantageous if theliner fastening mechanisms 158 are configured such that they tend toattach or couple with other portions of the washable diaper 110 or otherclothes, fabrics, fastening mechanisms, etc. For example, if the linerfastening mechanisms 158 are the hook portion of a hook and loopfastener, the liner fastening mechanisms 158 may tend to attach orcouple to other portions of the washable diaper 110 or other fabricswhen the washable diaper 110 is not worn, such as when the outer article120 is being washed. In such a configuration, however, the liner andopening fastening mechanisms 158, 158B may be removably mated or coupledsuch that the liner fastening mechanisms 158 (and opening fasteningmechanisms 158B) are blocked-off or otherwise rendered incapable ofcoupling to other portions of the washable diaper 110 or other fabrics,clothes fastening mechanisms, etc. Further, as explained above when theliner and opening fastening mechanisms 158, 158B are coupled or attachedthe opening 155 is “opened” to an extent. Such an “open” configurationmay be advantageous because it may allow the at least one absorbent pad170 to become easily disengaged from the cavity 154 through the opening155 when the inner liner system 140 is not assembled with the outerarticle 120 or the washable diaper 110 is worn. For example, the “open”configuration of the opening 155 via the liner and opening fasteningmechanisms 158, 158B may allow the at least one absorbent pad 170 to befreed from the washable article 150 when the washable article 150 isremoved or disengaged from the outer article 120 and the othercomponents of the inner liner system 140 and washed during a typicalwash cycle of a typical washing machine. In this way, the at least oneabsorbent pad 170 may advantageously not need to be handled or otherwisemanually removed from the washable article 150, such as when the atleast one absorbent pad 170 and washable article 150 are soiled.

As shown in FIGS. 14-15C and 17, the at least one washable article 150may include at least one first end stiffening member or portion 156positioned proximate to the first end thereof and/or at least one secondend stiffening member 157 being positioned proximate to second end 152thereof. In some embodiments, the least one first and second endstiffening members 156, 157 may include at least one stiffening member(not shown). The at least one stiffening member may be fabricated from amore rigid material than used for the fabrication of the at least onewashable article 150. Exemplary stiffing member materials may includefabric, plastic, metal, polymers, elastomers and the like. In theillustrated exemplary embodiment, the first and second end stiffeningmembers 156, 157 are stiffer portions of the washable article 150 ascompared to other portions of the washable article, and are formed bythe material of the washable article 150 being stitched and/or foldedover upon itself at least once. Although the first and second endstiffening members 156, 157 are illustrated at or near the first andsecond ends 151, 152, they may alternatively be positioned in anylocation and orientation and be formed in any manner.

The at least one washable article 150 may also include at least onecompartment fastening mechanism 153, as shown in FIGS. 14-15C and 17.The at least one compartment fastening mechanism 153 may be configuredto couple at least the at least one washable article 150 to the outerarticle 120, as described above. The at least one compartment fasteningmechanism 153 may be coupled to the washable article 150 by any means,and may take the form of any known fastening mechanism in the art. As anon-limiting example, the at least one compartment fastening mechanism153 may be at least one half or mate of a hook and loop fastener, suchas a Velcro® brand hook and loop fastener system, a hook and eyefastener, pin fastener, button fastener, snap button or claspmechanisms, or the like. As the at least one fastening mechanism 131 ofthe exemplary illustrated outer article 120 are one half or mate of apress, spring or snap button, the at least one compartment fasteningmechanism 153 may be the other half or mate of the press, spring or snapbutton such that the at least one fastening mechanism 131 of the outerarticle 120 and the at least one compartment fastening mechanism 153 arecapable of removably mating or coupling. Further, the number andpositioning of the at least one compartment fastening mechanism 153 ofthe washable article 150 may vary. For example, the at least onecompartment fastening mechanism 131 may be positioned proximate the sideand longitudinal edges of the washable article (e.g., a compartmentfastening mechanism 131 proximate each corner of the washable article150) to substantially align with the fastening mechanisms 131 of thefirst and second compartments 123, 124 of the outer article 120. In suchan arrangement, the compartment fastening mechanisms 153 allow thewashable article 150 to be removably coupled to the outer article 120such that the first and second ends 151, 152 of the washable article 150are removably coupled and secured within the first and secondcompartments 123, 124 of the outer article 120, respectively, as shownin FIG. 17. Further, because the at least one absorbent pad 170 may bepositioned within the cavity 154 of the washable article 150, the atleast one absorbent pad 170 may also be removably coupled to the outerarticle 120 via the compartment fastening mechanisms 131 and thefastening mechanism 153 of the outer article 120.

As shown in FIGS. 14-17, the at least one liner member 160 may also beconfigured with the at least one washable article 150 such that theliner member 160 is secured to the outer article 120 via the compartmentfastening mechanisms 153 of the washable article 150 and the fasteningmechanism 131 of the outer article 120, as well as the at least oneliner fastening mechanism 158 of the washable article 150. As shown bestin FIGS. 15A-C, the at least one liner member 160 may define a first end171 and a second end 172 and a longitudinal length therebetween. Thelongitudinal length of the liner member 160 may be substantially similarto the longitudinal length of the washable article 150 extending betweenthe first and second ends 151, 152 thereof. The width of the linermember 160 may be substantially greater to the width of the washablearticle 150. In other embodiments however, the length of the linermember 160 may be greater to or less than that of the washable article150, and/or the width of the liner member 160 may be equal to or lessthan that of the washable article 150.

With reference to FIGS. 15A-C, when one embodiment of the washablediaper 110 is assembled, the at least one absorbent pad 170 is insertedthrough the opening 155 and into the cavity 154 of the washable article150. As shown in FIG. 15A, once the absorbent pad 170 is positionedwithin the washable article 150, the top surface (not shown) of thewashable article 150 may be positioned on the at least one liner member160 such that the first and second ends 151, 152 of the washable article150 substantially align with the first and second ends 171, 172 of theliner member 160 and the washable article 150 is positioned in a medialportion of the width of the liner member 160. Due to the width of theliner member 160 as compared to the width of the washable article 150and the positioning of the compartment fastening mechanisms 153, theportions of the width of the liner member 160 that expand past the sideedges of the washable article 150 may be folded over the washablearticle 150 such that the liner member 160 at least lies over andsubstantially covers the compartment fastening mechanisms 153 as shownin FIGS. 15B and 15C. As shown in FIGS. 15B-16, once the liner member160 is wrapped or folded over the width of the washable article 150, theliner fastening mechanisms 158 of the washable article 150 may engagethe liner member 160 at a medial portion of the length of the linermember 160, for example, to at least initially removably secure orattach the liner member 160 to the washable article 150 (and thereby theabsorbent pad 170).

Once the liner member 160 is wrapped about the washable article 150 (andtherefore the top surface (not shown) of the washable article 150substantially covers by the liner member 160) and the liner fasteningmechanisms 158 of the washable article 150 engage the liner member 120,the inner liner system 140 may be considered formed, constructed orassembled, as shown in FIG. 17. As also shown in FIGS. 10 and 17, theinner liner system 140 may be coupled to the outer article 120 to formthe washable diaper 110 when formed, constructed or assembled. Asillustrated in FIG. 17, the compartment fastening mechanisms 153 of thewashable article 120 and the fastening mechanisms 131 of the outerarticle 120 may be coupled with the liner member 160 held therebetween.In this manner, the inner liner system 140 can be detachably secured orcoupled to the outer article 120 such that the first end 141 of theinner liner system 140 and an adjacent portion thereof is positioned andselectively secured within the first or front compartment 123, and suchthat the second end 142 of the inner liner system 140 and an adjacentportion thereof is positioned and selectively secured within the secondor back compartment 124, as shown in FIG. 10. More specifically and alsoillustrated in FIG. 10, the inner liner system 140 can be detachablesecured or coupled to the outer article 120 such that the first or frontends 151, 171 of the washable article 150 and the liner member 160 andadjacent portions thereof are positioned and selectively secured withinthe first or front compartment 123, and such that the second ends 152,172 of the washable article 150 and the liner member 160 and adjacentportions thereof are positioned and selectively secured within thesecond or back compartment 124. Further, the inner liner system 140 maybe held within the medial portion of the width of the outer article 120by the side barriers 127, 128.

So that the washable article 150 is capable of securing to the outerarticle 120 via the compartment fastening mechanisms 153 of the washablearticle 120 and the fastening mechanisms 131 of the outer article 120,in some embodiments the liner member 160 may have a thickness,flexibility and other properties that allows for liner member 160 to besecured between compartment fastening mechanisms 153 and the fasteningmechanisms 131 without effectively altering their fasteningcapabilities. Alternatively, liner member 160 may include apertures (notshown) aligned with the compartment fastening mechanisms 153 and thefastening mechanisms 131 so that they can be coupled together throughthe liner member 160.

In the illustrated exemplary embodiment, the liner member 160 isgenerally compliant, soft feeling, and non-irritant to the wearer'sskin. In some embodiments, the liner member 160 may be fabricated from aliquid pervious material, including but not limited to, rice paper,cellulose fibers, blend of rayon and cellulose fibers and any othernatural or synthetic liquid permeable hydrophobic fibrous materials thatwill allow liquid to readily penetrate through its thickness. The linermember 160 may also be fabricated from a material that will wickmoisture away from the wearer's skin. The liner member 160 may furtherbe fabricated from any material that is biodegradable and flushablethrough a regular toilet system. When the liner member 160 is fabricatedfrom a liquid pervious, flushable material, it may function to containnon-liquid bodily excrements and allow for easy disposal via a regularseptic/sewer system, as well as allow liquid excrement to pass throughthe liner member 160 and into the washable article 150 and absorbent pad170.

As shown in FIG. 19, the outer article 120 may include any design oraesthetic pleasing ornamentation on the outer surface or layer 130. Forexample, the outer surface or layer 130 may include a design, such as apattern or depiction that an adult or child would find aestheticallypleasing. As another example, as shown in FIG. 19 the outer surface orlayer 130 may include ornamentation 190 detachably or permanentlycoupled thereto that resembles a pocket or other typical “adult”clothing characteristics, such as one or more pocket positioned on theouter surface or layer 130 of the outer article. In some embodiments,the pocket ornamentation 190 may be detachable, and only one pocketornamentation 190 may be provided on the back side of the outer surfaceor layer 130 of the outer article 120. Further, in some embodiments theornamentation 190 on the outer surface or layer 130 of the outer article120 may serve a utilitarian purpose, such as for storage,identification, style or the like.

Turning to FIGS. 20-22, an exemplary partial method of manufacturing anouter article is shown, and the outer article is generally indicated bythe reference numeral 320. Exemplary outer article 320 is similar to theembodiments of exemplary outer articles 20, 120 and 220 described abovein connection with FIGS. 1-19, and therefore like reference numeralspreceded by the number “3”, as opposed to the number “1” or “2”, areused to indicate like elements. Like exemplary illustrated outerarticles 20, 120 and 220, exemplary illustrated outer article 320 may beassembled with an inner liner system (no shown) to form a washablediaper (not shown). The description above with reference to exemplaryouter articles 20, 120 and 220 may therefore apply to particularcomponents, systems, features or the like of exemplary outer article 320and is not repeated hereinafter for brevity.

As shown in FIG. 20, a method of manufacturing an outer article 320 maycomprise the step of removing, forming or otherwise manufacturing agenerally hourglass-shaped stock 392 of liquid pervious material ormaterials. When formed of liquid impervious material, the generallyhourglass-shaped stock 392 may be the inner layer 329 of the outerarticle 320. In some other embodiments, the generally hourglass-shapedstock 392 may be the outer layer 330 of the outer article 320. Forexample, if the generally hourglass-shaped stock 392 is not formed fromliquid impervious material, the generally hourglass-shaped stock 392 maybe an outer layer 330. The generally hourglass-shaped stock 392 may bedirectly removed from a single piece of liquid pervious material, or maybe removed in stages or steps. Further, in some embodiments multiplehourglass-shaped stocks 392 are removed from liquid pervious material atthe same time, such as stamping a stack of liquid pervious material witha cutter that is shaped substantially similar to the hourglass-shapedstock 392. In some embodiments a template shaped substantially similarto the hourglass-shaped stock 392 may be used to obtain, produce orotherwise manufacture the hourglass shaped stock 392 of liquid perviousmaterial or materials.

The hourglass-shaped stock 392 may include the first and second portions385, 386 of the first and second compartments 323, 324 as adjacentintegral components. In the illustrated exemplary embodiment of thehourglass-shaped stock 392 the first and second opposing extendedportions 336, 337 of the first and second portions 385, 386 may includefirst and second interior extending portions 336B, 337B, respectively,to delineate the first and second portions 385, 386, as best shown inFIG. 20. As explained further below, the first and second interiorextending portions 336B, 337B may facilitate the forming or manufactureof the first and second liquid pervious compartments 332, 334. Inalternative embodiments, the first and second portions 385, 386 of thefirst and second compartments 323, 324 may be formed separately, such asforming the hourglass-shaped stock 392 with the first portions 385 andforming the second portions 386 separately (i.e., the second portions386 may be discrete). Similarly, as shown in FIG. 20 the opposing sidebarriers 327, 328 may be formed separately from the hourglass-shapedstock 392 as side barriers stock 392B. However, in alternativeembodiments the hourglass-shaped stock 392 may include the opposing sidebarriers 327, 328 integral therewith, as indicated by the dashed line326 as compared to if the opposing side barriers 327, 328 are formedfrom separate and distinct side barrier stock 392B, as shown in FIG. 20.

Once an hourglass-shaped stock 392 of liquid impervious material isformed, the hourglass-shaped stock 392 can be further formed into anouter article 320 through additional processing steps. For example, asshown in FIG. 21 the opposing side barriers 327, 328 may be coupled tothe opposing sides 325, 326 of the hourglass-shaped stock 392. In someembodiments, the opposing sides 325, 326 of the hourglass-shaped stock392 may be coupled to the opposing sides 325, 326 of thehourglass-shaped stock 392 by stitching (i.e., sewn thereto). As alsoshown in FIG. 21, the second portions 386 may be folded over the firstportions 385 toward the medial portion 339 of the hourglass-shaped stock392 at the first and second interior extending portions 336B, 337B. Assuch, the first and second interior extending portions 336B, 337B may beused as a guide as to where the second portions 386 should be foldedover the first portions 385. Thereby, the “fold-line” formed by placingthe first and second portions 385, 386 in aligned abutment forms thefirst and second ends 321, 322 of the outer article 320 and a liquidimpervious bottom edge to the first and second compartments 323, 324,respectively.

With the first and second portions 385, 386 in aligned abutment with thesecond portion 386 overlying the first portion 385, the side edges ofthe first and second compartments 323, 324 may be sealed such that theyare liquid impervious. For example, as shown in FIG. 22, liquidimpervious material or portions 380 may be affixed over the side edgesof the first and second compartments 323, 324 such that the side edgesare substantially liquid impervious. In this way, the side edges andfirst and second ends 321, 322 of the first and second compartments 323,324, respectively, are liquid impervious and the portion facing themedial portion 339 of the outer article is “open”. In such anembodiment, fastening support members 382 with liner system fasteningmembers 331 may be coupled within the first and second compartments 323,324. For example, liquid impervious material or portions 380 may beaffixed over the front and back sides 321, 322 such that the front andback sides 321, 322 are liquid impervious, and the fastener supportmembers 382 may be coupled to the outer article 320 via the affixing ofthe material or portions 380. In some embodiments, the liquid imperviousmaterial or portions 380 may be banding stitched over the front and backsides 321, 322 with non-wicking thread, and the fastening supportmembers 382 may be positioned adjacent the front and back sides 321, 322between the first and second portions 385, 386 such that the threadaffixes the banding, first and second portions 385, 386 and fasteningsupport members 382 together. In some embodiments, the thread ispolyester thread sewn via a ball needle.

As also shown in FIG. 22, the liquid impervious material or portion 380may be applied over the edges and substantially about the perimeter ofthe outer article 320, including the side edges 325, 326 where theopposing side barrier 327, 328 are coupled to the outer article 320. Incontrast, however, the outer edges of the opposing side barrier 327, 328may not include the liquid impervious material or portion 380. Instead,the outer edges of the opposing side barrier 327, 328 may include anelastic member 388 coupled thereto. For example, the elastic member 388may be couple to the outer edges of the opposing side barrier 327, 328in an elongated or stretched orientation or state, such that in aneutral position the elastic member 388 may act to shorten thelongitudinal length of the opposing side barrier 327, 328. In this way,the opposing side barrier 327, 328 may act to cup or bowl the outerarticle 320 into a shape that is conducive to being worn as a washablediaper 310. Further, the manner which the opposing side barrier 327, 328are attached to the side edges 325, 326 of the washable article 320,such as by banding being sewn over the edges thereof, may tend toencourage or promote the opposing side barrier 327, 328 from extendingaway from the inner surface or layer 339. In such a configuration, theopposing side barrier 327, 328 may be effective in preventing leakagefrom the interior of the washable article 320 and enhance the comfortand fit of the washable article 320 to a user.

The outer article 320 may include further processing, such theapplication of fastening mechanism configured to allow the outer article320 to be wrapped around a users waist and legs and removable coupledthereto. Further, covers or shields for the fastening mechanisms mayalso be provided to prevent the fastening mechanism from inadvertently“coupling”, such as when the outer article 320 is washed. Still further,the washable article may include several layers, and such layers may becoupled together via one or more independent step, or during one of thepreviously discussed steps. For example, the application of the liquidimpervious members or portions 380 may be effective in coupling severallayers of the outer article 320 to one another.

As may be recognized by those of ordinary skill in the pertinent artbased on the teachings herein, numerous changes and modifications may bemade to the above-described and other embodiments of the presentinvention without departing from the spirit of the invention as definedin the claims. For example, the components of the washable diaper may bemade of any of numerous different materials that are currently or laterbecome known for performing the functions of such components.
